This is the first time I have a problem with StartIsBack. I'm using the latest + 1.5 version. When I click on a Start Menu item that requires User Account Control certification (like Regedit), both the Start Menu and the User Account Control warning disappear. I can see the User Account Control shortcut pinned to the taskbar, but it doesn't work. I have to again click the start button and then the User Account Control warning appears and I can click on it to allow the operation. Perhaps I have to check or uncheck something? Thanks
